While the Jack Casady Bass continues to pretty much dominate the cool factor when it comes to the best rock and pop artists around, one of the Casady's biggest fans turns out to be a drummer, Dave Grohl. Grohl used his Ebony Jack Casady for all his promotional concerts for his documentary on legendary recording studio Sound City. And Grohl will host a new untitled series for HBO that will visit studios in Chicago, Austin, Nashville, Los Angeles, Seattle, New Orleans, Washington D.C., and New York.

The series will also celebrate the Foo Fighters 20th anniversary. Grohl describes the series as a "love letter to the history of American music" and already Heart's Nancy Wilson--a long time Epiphone fan--Fugazi's Ian MacKaye, and KISS' Paul Stanley are confirmed guests. Stay tuned for more info.
